By Robert Sanders, University of California, Berkeley Millimeter-size marine organisms called foraminifera have been used to monitor pollutants in marshes and oceans, and could help to assess recovery in the Gulf of Mexico following the three-month long Deepwater Horizon oil spill. That was the message from a French/American team of researchers who recently reported on the health of French marshes and mudflats 32 years after the Amoco Cadiz spilled 220,000 tons of oil along the Brittany coast...

By Wendy Leonard Deseret News After digging around in central Utah's desert, high school students enrolled in Westminster's Paleo Camp cleaned and studied the various fossil rocks they had found. "If you want to study the history of life on Earth, this is the place to do it," said Dave Goldsmith, a geology faculty member at Westminster. He chaperoned the group of ninth- to 12th-graders to a fossil quarry at Antelope Springs in Sevier County last Tuesday, then taught them about their...

By Dong, Lin Xiao, Shuhai; Shen, Bing; Zhou, Chuanming Abstract: Horodyskia is one of the earliest known macroscopic life forms, with a fossil record dating from c. 1.4 Ga. Palaeopascichnus represents a key Ediacaran element with world-wide distribution. However, their body constructions and affinities are poorly understood, partly because previously described species are mostly preserved as casts and moulds in siliciclastic rocks. Silicified specimens from the upper Ediacaran Liuchapo...

By Hofmann, H J O'Brien, S J; King, A F ABSTRACT- Newly found fossils in the Conception and St. John's groups of the Bonavista Peninsula considerably extend the known geographic distribution of the Ediacaran fossils in Newfoundland. They occur in deepwater sediments and are preserved as epireliefs, forming census populations underneath volcanic ash layers throughout a more than 1 km thick turbiditic sequence. The exposed fossiliferous units comprise the Mistaken Point, Trepassey, Fermeuse,...

The abundant diversity of characteristics within species likely helped fuel the proliferation and evolution of an odd-looking creature that emerged from an unprecedented explosion of life on Earth more than 500 million years ago. University of Chicago paleontologist Mark Webster reports this finding in the July 27 issue of the journal Science. "From an evolutionary perspective, the more variable a species is, the more raw material natural selection has to operate on," said Webster, an...

Scientists at the University of Chicago and the National Museum of Natural History in Washington, D.C., have produced new evidence to finally resolve the mysterious identity of what they regard as one of the weirdest organisms that ever lived. Their chemical analysis indicates that the organism was a fungus, the scientists report in the May issue of the journal of Geology, published by the Geological Society of America. Called Prototaxites (pronounced pro-toe-tax-eye-tees), the organism went...
